To all whom it may concern,.- A

Be it known that I, ISAAC N. BOWEN, acitizen of the United States,residing at-Lead, in the county of Lawrence and State of South Dakota,have invented new and useful Improvements in Tires, of which thefollowing is a s ecification.

he invention relates to an im rovement in tires7 particularly to theresi ient type designed to counteract shock or jars incident tothetravel of a vehicle.

The main object of the invention isthe production of a resilient tire ofmetallic construction formed in sections and so supported from thewheel-rim as to readily yield under the influence of any jar or thelike.

The invention in its preferred form will be described in the followingspecification, reference being had lto the accompanying drawin s,wherein-v igure 1 is a view in side' lelevation of a portion of a wheelprovided with my improved tire. Fig. 2 is an enlarged transversesectional view of the same. Fi 3 .is a broken longitudinal sectionalview il ustrating the end connection of the tire-sections. Fig. 4 is aperspective view of one of the tiresections. Fio. 5 is a view in sideelevation of a portion of a wheel. showing my improved tire providedwith means to preventlateral slipping of the wheel.

Referring to the drawings, wherein like numerals of reference designatelike. parts throughout the several views, myim roved tire comprises *anVinner section, hereinafter termed the rim and an outer section,hereinafter termed the tire proper. The inner section preferablycomprisesa U-shaped metallic rim 1, designed to be suitably secured tothe felly 2 of a wheel. The side plates 3 of the rim roject radiallybeyond the felly,

roun ing the telly, as clearly shown in Fig. 2. The tire pr'o er is madein short sections 4, referably o metal and of inverted-U shape. hedistance between the inner surfaces of the side plates 5 ofthetire'Lsect-ion is slightly greater than the exterior dimension o therim, whereby said tire-section is designed to embrace the sides 3 of therim. Each side gitudinal slot 6, designed to receive a T- shaped bushing7, the inner end of which latter is coincident with the inner surface ofthe side plates 5, while the, head 8' of said bushing overlies the outersurface of said side minally bearing a azinst the tread-p ate andagainst therim an serving to normally maintain the tire-sections attheir limit of outward movement. Each tiresection is reduced at V oneend, as at 15, the adjacent end of the adjoining section being recessed,as at 16, to 'receive said reduced end 115, whereby the sections are resectively equipped in a manner to permit t eir independent slidingmovement under the influence of the springs 14 and prevent theircomplete separation or disen agement. j

o revent lateral slipping of the wheel provi ed with m`y improved tire,I prefer to secure on theouter surface of the tread 12 i of eachtire-section what I term an antiskiddingy late 17, provided with alongitudinal r1 18 and with transverse projections 19, formedby severingthe plate and bending the severed portion outward,` as clearly shown inF' 5. By the use of these plates, which may e arran ed one to eachtire-section or in any desire number, skidding of the wheel isprevented. In use the respective sections as they contact with theground will yield to the weight against the stress of the spring14,1'endering'the tire practically 4as resilient and yielding as theusual pneumatic or cushioned tire, it being evident that vpracticallyall movement incident to the jar oi the vehicle will be taken up by thespring 14 to the particular tire-section subJected to the strain,obviating the transference thereof to the body of the wheel or vehicle.The sections are wholly independent and yet slidably connected in'orderto permit their independent movement and at the same time prevent theirabsolute separation.

Having now described my invention, what I claim as new, and desire tosecure by Let l ters Patent, is- 1. A 'tire comprising a U-shaped rim, a

plurality of tread-sections telescopically connected together, each `ofsaid sections comprising a tread portion and side plates projectingtherefrom and having one end reduced internally and the otherexternally, said side pla-tes being designed to it over the U-shapedriin and rest against the outer surface thereof, means adjusta-blyconnecting said side plates'to the ri; end springs se.- fxurecl Withinthe rim and ming against the tread ortion of the sections.

2. Wheel-tire comprising Usliaped rim a plurality ofinverted-U-shazipedl tread-sections'overlap in the rim and movablysecured theretobyzobolts, said sections being reduced internally at oneend and externally at the other, said externally-reduced ends i 5 thetread-sections anclproj eating downwardly through the coil-springs.

In testimony whereof l affix my signature in presence of two witnesses.
